PICK ... kinda depends on your POV as to whether all records are in one table or not. Easier to just think of each record as a long string, with delims marking fields/subfields/etc. MV records are usually not all THAT long so straight searching goes quick but you COULD add a small hash table if there were mass quantities of fields/subfields. Anyway, get or borrow a MV DB and fool around with it yourself.
